2019CrosstrekOwner

Hi, I just bought a 2019 Crosstrek. I love it so far. Does anyone know how to disable to Seatbelt Warning Chime? I emailed Subaru and they told me to ask the dealer. I asked the dealer and the method they told me (buckling and unbuckling the seatbelt 20 times in 30 seconds, etc) did not work. Does anyone know how to disable this function? Thanks very much in advance, Jason
